The following are feeding books I wish I had read at the very beginning. They are essentially about how learning to eat is a developmental process and not just a physical thing that has to be done. The more autonomy you give your child in the feeding process, the more feeding competency they should develop without creating unhealthy emotions towards eating that can lead to feeding disorders.

If your child has already developed an issue, you will probably want to read this one:

CONSTIPATION, SOILING, WETTING, ACCIDENTS
Constipation is a major psychological vicious cycle once it develops. I would advise being very aggressive in dealing with constipation at the first whiff of it. A single instance of constipation can cause a child to start withholding, and therefore creates a vicious cycle of further constipation and further withholding, that is very difficult to break.It's No Accident
is a good primer on the dangers of constipation and its relationship to soiling, wetting, and also a good intro to bathroom issues in schools and issues to think about in potty training. Once you see what kids with constipation have to deal with, you won't want to let your kids get it. There are kids that are on Miralax or other treatment protocols for 10+ years, unable to resolve their constipation issues.

Tip: adding large amounts of organic prune juice (pure prune juice, not a juice blend) to your baby's milk is a good way to keep their stool soft. Err on the side of caution!
